SPOKE-EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 277,991, dated May 22,1883.

Application filed February 24, 1883 (No model.) d

To all whom it may concern:

Be it known that I, ROBERT N. CAUGHELL, of Shedd, county of Linn, Stateof Oregon, have invented an Improved Spoke-Extractor; and I herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to a new and useful device for removing spokes fromthe hub; and it consists in a peculiar clamping-ring fitting the spokeandactin g as a lever, having a fulcrum on the hub, and a means forapplying the power at the outer side, as will hereinafter fully appear.

The object of my invention is to remove spokes from the hub withfacility and effectiveness.

Referring to the accompanying drawing, the figure is a view of mydevice, showing its application.

A represents the hub of a wheel, in which the spoke a is secured in theusual manner.

B represents a ring having oppositely-extending arms 1). Through thesides of this ring fit set-screwsc, on the ends of which are looselyfitted the clamping-jaws (J. These jaws are preferably made with concavefaces to better adapt them to fit the spoke. They are, as I have beforesaid, loosely fitted on the set-screws, and this may be done in anysuitable manneras, forinstance, by heading down the end of the screw onits face, and having a shoulder against its back, thus providing for theimpingement of the screw against thej aw, and also for the movement ofthe ring after the jaws are clamped upon the spoke.

Pivoted to one arm I) ofring B is a stout bar or'rod, D, the end ofwhich is curved to conform to the surface of the hub, against which itbears. In the other arm I) is pivoted a nut, e, through'which a longscrew, E, passes. The upper end of this screw is provided with a crank,f, and the lower end with a bearing, g, loosely fitted upon it. Thisbearing is curved to better fit the hub, and, by reason of being fittedloosely upon the screw the latter may turn, while the bearin g remainsstationary against the hub.

- In using the device the ring B is first clamped tightly to the spokeby means of the jaws G,

I and the rod or bar D bears against the hub.

The screw E bears against it on the other side, and by operating thecrank f the arm I), through which the screw E passes, is forced up, thusgradually changing the inclination of the ring B, which is in fact alever, its ful' crum being against the hub through the bar D, and thespoke to which it is clamped being the weight. This change ofinclination is possible because of the loosely-mounted jaws O,

as explained, and as the change is eifected the spoke is drawn out fromthe hub. The pivoted nut 0 permits the operation of the screw E to beunaffected by the movementof the ring, so that the latter may change itsin: clination while the screw maintains its bearing. There is also anadvantage in the pivoted nut, in that it allows the screw E to find themost desirable bearing upon the particular hub, and in all cases permitsit to bear as close to the base of the spoke as possible, whereby thebest position may be obtained.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, isr 1. In a spoke-extractor, the swinging ringB, clamped to thespoke,.the bar or rod D, bearing on the hub and actingas a fulcrum for the ring 0, in combination with a means for applyingpower to the other side or end of the ring to move it on its fulcrum anddraw the spoke, substantially as herein described.

2. Inaspoke-extraeter,thering B,havingsetscrews 0 and jaws O, looselymounted thereon, whereby said ring may be clamped and pivoted upon thespoke, and the fulcrum bar or rod D, pivoted to one side of the ring andbearing against the hub, in combination with means connected with theother side of the ring to move it upon its fulcrum, substantially as andfor the purpose herein described.

3. A spoke-extractor consisting of the ring B, pivoted and clamped uponthe spoke, the fulerum-rodD,pivoted to the ring on one side and bearingagainst the hub, and the operating-screw E, pivoted to the ring on theother side and bearing against the hub, substantially as hereindescribed.

4. A spoke-extractor consisting of the ring wiser 13 having the sidearms, I), the set-screws c, and bearing upon the hub, substantially asand jaws U, loosely fitted on said screws, herein described.
